A photog has filed a lawsuit against P!nk and her husband Carey Hart in the wake of their nuclear brawlback in June ... claiming he was physically beaten and humiliated during the fight ... and even called a "pedophile."

Boris Issaei claims he was trying to snap P!nk while she was changing her daughter's diaper in a playground at the Malibu Country Mart... and P!nk's husband Carey snapped, saying, "You f***ing c*** ... You f***ing pedophile." P!nk allegedly added, "You're photographing my baby naked."

Boris says Carey's friend then went on the attack ... kicking him in the shin, stomping on his feet, and kneeing him in the groin. He claims his camera equipment was damaged during the melee.

Boris claims P!nk even added insult to injury, insisting Boris deserved the beating for his actions.

He's suing for assault and battery, and destruction of his camera equipment ... demanding unspecified damages.

We posted video of the altercation soon after it happened, showing Carey's friend attacking him. Cops were called to the scene, but no arrests were made.
